On Friday evening, the 22nd of May at 17:53 CEST, NavSAS researchers successfully acquired and tracked the Galileo E1b signal transmitted by the Galileo satellite GSAT204 (PRN 22). GSAT204 was recently launched, together with GSAT203, on 27th March 2015 from French Guyana (here the ESA news).
This acquisition was performed using NGene2, a GNSS fully software real-time receiver running on a general purpose processor and completely developed by NavSAS group.
During the data collection NGene2 was also able to acquire and track signals broadcasted by Galileo satellite GSAT202 (PRN 14), launched together with GSAT201 on the 22nd August 2014 and initially injected in a not nominal orbital plane. At the moment of the data collection and signal acquisition no valid navigation messages were transmitted from GSAT202 and GSAT204.
Galileo system now has eight satellites in orbit. More information on Galileo and on the next launches on the European Space Agency dedicated website.
